Overview
NRC heaters serve hydraulic/lubricating fluids and other non-corrosive liquids. Fins substantially increase heat-transfer area, reducing heat output per unit surface area and helping prevent oil carbonisation. The assembly comprises a metal-sheathed tubular heating element, a seamless steel protective sleeve with metal fins, and a gasket. The asbestos-rubber gasket material is rated to 300 °C.
Selection and operation
The heating section must be fully immersed; heating a moving liquid is preferred. Select the power according to the oil, viscosity and cold-start conditions.
